摘　　要：钢球抛落运动中,落点的动能起破碎作用,而落点的径向动能又起主要破碎作用。以各球层径向动能因子累积值最大为目标求得的转速率是球磨机的最优转速率。In the throw and fall course of the steel ball, the kinetic energy of the dropping point acts as the crushing function, the radial kinetic energy acts as the main crushing function. The rotation velocity that is gotten by aiming at the maximum accumulative value of the kinetic energy factors of each layer of ball is the optimal rotation velocity of the ball mill.

关 键 词：球磨机 转速率 径向动能因子
